FAYETTEVILLE, N.C. - A 20-year-old woman in the U.S. Air Force who alleged three airmen raped her in North Carolina now faces a court-martial for drinking and lewd behavior.

Airman Cassandra Hernandez, 20, complained she had been at a party in May 2006 and drank too much. She told officers despite having a fuzzy memory, she recalls being sexually assaulted by three other airmen at their dorm.

The men denied the charges, saying the sex was consensual, and by the time the hearing took place in December, Hernandez told CBS she lost her nerve and didn't testify.

The charges against the men were dropped. Hernandez has since been charged with dereliction of duty for underage drinking and indecent acts for engaging in sexual activity with an airman in front of two other airmen.

The three airmen she accused will testify against her and have been granted immunity, the report said.

If found guilty on Sept 24, Hernandez could face jail time, lose pay, rank and possibly be discharged from the Air Force.
